\(NaHCO_3+HCl\rightarrow NaCl+CO_2+H_2O\)
\(NaHSO_3+HCl\rightarrow NaCl+SO_2+H_2O\)
Ta có :
\(n_{HCl}=0,2.1=0,2\left(mol\right)\)
\(hh:NaHCO_3\left(amol\right);NaHSO_3\left(bmol\right)\)
Giải hệ phương trình :
\(\left\{{}\begin{matrix}84a+104b=18,8\\a+b=0,2\end{matrix}\right.\Rightarrow\left\{{}\begin{matrix}a=0,1\\b=0,1\end{matrix}\right.\)
\(\Rightarrow n_{CO2}=n_{SO2}=0,1\left(mol\right)\)
\(\Rightarrow\%V_{CO2}=\%V_{SO2}=50\%\)
